Perhaps. But I think Etag, If-Modified-Since or whatever headers only make sense to a cache server that is designed to use these values, not for a generic one or the end users browser clients. And the last one is the real place caching-related headers making sence to. If I understand correctly, the Expires header can only give the client an impression how ofter a page is updated. > I would use "Expires" and "Cache-Control" for cache control. > Only when you want to disable the cache function, can these two headers be useful.
